Description

The following correct CSS was taken from MDN:s example:

#mydiv {
    clip-path: path('M 0 200 L 0,75 A 5,5 0,0,1 150,75 L 200 200 z');
}

https://developer.mozilla.org/en-US/docs/Web/CSS/clip-path

The validator incorrectly gives this error:

Error: clip-path: path('M 0 200 L 0,75 A 5,5 0,0,1 150,75 L 200 200 z') is not a clip-path value.

At line 2, column 68

75 L 200 200 z');↩}↩</style>
